This base-mounted end suction pump incorporates a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a dry shaft design, which prevents fluid contact with the stainless steel shaft through the use of a replaceable bronze shaft sleeve. Mechanical sealing consists of a ceramic seat half with EPT rubber, rated for a pressure of 125 PSI without a wear ring. Integral mounting feet on the casing provide structural stability, while pressure tappings allow for monitoring at the suction and discharge connections.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding on a 380-460V, 3PH power supply, resulting in a DOE PEI of 0.46. The 'S' in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
